# Auto Batch Code

When clicking 'Brew' to start a 'Brew Session', a batch code is automatically applied to the session. 

Auto-batch codes takes the first letter or number from each word or number in the name of the recipe to create an abbreviation for ‘Brew Sessions’, and then auto increments each ‘Brew Session’ by the number of times brewed. E.g. The first two ‘Brew Sessions’ of recipe named The Best Beer increment as TBB001 and TBB002.
